Hydrogen water is regular water infused with extra molecular hydrogen gas (H₂). It’s produced through electrolysis or by dissolving magnesium-based stick packs, allowing water to retain dissolved hydrogen that may offer antioxidant properties.

Emerging research suggests molecular hydrogen may reduce oxidative stress, thereby enhancing athletic recovery, improving cognition, and reducing inflammation, among other benefits. However, results are preliminary and not definitive.

Some users notice benefits within days or weeks, especially for recovery or hydration. Clinical studies often report noticeable effects after 4–12 weeks of regular use.

here are over 1500 studies, including more than 200 in humans, examining the effects of molecular hydrogen on oxidative stress, metabolism, recovery, inflammation, and other biological processes. For more information, visit www.hydrogenstudies.com.

Yes, but in water, hydrogen is chemically bound to oxygen. Molecular hydrogen (H₂) is a different form altogether. Hydrogen water is regular water infused with extra molecular hydrogen gas.

Hydrogen doesn’t accumulate in the body; it’s active for a short window and then cleared. That’s why we suggest intermittent use, drinking 2–3 glasses per day spaced across the day. This approach mirrors how hydrogen is studied and how oxidative stress naturally fluctuates during daily life.

Molecular hydrogen has been widely studied and is generally recognized as safe (GRAS). In some individuals, very high intake may cause mild digestive discomfort, such as bloating or loose stools. If you have specific health concerns or sensitivities, consider consulting a healthcare professional to determine what works best for you.

Hydrogen water tastes just like water. It has no added flavor, no aftertaste, and no change in texture. Just clean, refreshing hydration.

No. Hydrogen water contains dissolved H₂ gas and is pH-neutral. Alkaline water is defined by high pH levels and lacks consistent research support.

You can increase your intake of molecular hydrogen by drinking hydrogen-enriched water generated through electrolysis or magnesium-based stick packs. You can also inhale hydrogen gas and, in some cases, increase production of hydrogen gas by the microbiome by eating more fermentable fibers.

PPM stands for 'parts per million,' a unit measuring the concentration of hydrogen gas in water. A concentration of at least 0.5 PPM (equal to 0.5 mg/L) molecular hydrogen is considered therapeutic.

The Echo Flask generates up to 6 PPM of dissolved hydrogen from a 10‑minute cycle and up to 8 PPM in a 20‑minute cycle.

Yes. The Flask is certified to produce 8 PPM hydrogen based on third-party testing.

Test Results

Our flask generates molecular hydrogen (H2) fresh each time you run a cycle. The electrolysis process generates H2 directly from the water you put in. There are no cartridges to replace and no added chemicals or minerals are needed.

Only use deionized (DI) or reverse osmosis (RO) water with the flask.

No. The Flask maintains a neutral pH and does not introduce metals into the water.

For best performance and long-term reliability, we recommend using plain water only in the Flask. Adding flavorings, supplements, or powders inside the device can interfere with the electrolysis process and may shorten the life of the unit. If you prefer flavored water or supplements, enjoy them after generating hydrogen water by mixing them in a separate container. Please note that adding ingredients or stirring may reduce the amount of dissolved hydrogen, as hydrogen naturally escapes from water over time. For the highest hydrogen levels, enjoy your hydrogen water soon after it’s made.

No. The Echo Flask must be handwashed only. Avoid dishwashers and submerging the device.
